Title: Solution spinning process
IPC: D01F6/62
Filed: 1989-09-08
Abstract: This invention discloses a process for producing a 
high modulus, high tenacity polyethylene terephthalate 
filament which comprises (1) spinning a solution of 
polyethylene terephthalate in an organic solvent 
through a die to produce a solution spun filament, 
wherein the polyethylene terephthalate has an intrinsic 
viscosity of at least about 3.0 dl/g and wherein the 
organic solvent is selected from the group consisting 
of (a) hexafluoroisopropanol, (b) trifluoroacetic acid, 
(c) mixed solvent systems containing from about 20 
weight percent to about 99 weight percent 
hexafluoroisopropanol and from about 1 weight percent 
to about 80 weight percent dichloromethane, and (d) 
mixed solvent systems containing from about 20 weight 
percent to about 99 weight percent trifluoroacetic acid 
and from about 1 to about 80 weight percent 
dichloromethane; and (2) subsequently drawing the 
solution spun filament to a total draw ratio of at 
least about 7:1 to produce the high modulus, high 
tenacity polyethylene terephthalate filament. The 
filaments made by the process of this invention have 
better thermal stability, such as a lower thermal 
shrinkage and a higher melting point, than fibers made 
utilizing standard melt processing techniques.

Title: Silicone-polycarbonate block copolymers
IPC: C08G64/18
Filed: 1990-02-23
Abstract: Silicone-polycarbonate block copolymers are pro­
vided resulting from the reaction of certain siloxy aromatic 
imide siloxanes or hydroxyaromatic ester siloxanes which are 
made by effecting reaction between an organosiloxane having 
terminal aromatic anhydride groups or aromatic haloacyl 
groups which are each attached to silicon by silicon arylene 
linkages with an appropriate bishydroxyarylene compounds or 
hydroxyarylene amino compound. The aforementioned 
hydroxyaromatic imide siloxanes or hydroxyaromatic ester 
siloxanes are then phosgenated with a dihydric phenol or an 
aromatic bischloroformate. The silicone-polycarbonate block 
copolymers have been found to be flame retardant and useful 
as dielectric films and membranes, and as flame retardants in 
aromatic polycarbonates..

Title: A hydraulic active suspension system for a vehicle capable of enhancing both the comfortability and the controllability of the attitude of vehicle body
IPC: B60G17/016
Filed: 1990-03-01
Abstract: In a hydraulic active suspension system, a plurality of 
actuators (1FR, 1FL, 1RR, 1RL) having working fluid 
chambers (2FR, 2FL, 2RR, 2RL) are provided corresponding 
to vehicle wheels. Each actuator is adapted to increase or 
decrease vehicle height in response to the hydraulic pressure 
within its working fluid chamber. The hydraulic pressures within 
the working fluid chambers are controlled to their desired 
pressure by associated pressure control devices. A desired 
pressure computing device is further provided. The computing 
device calculates the actual values of roll, pitch, heave and warp 
of a vehicle body from the vehicle heights detected by detecting 
devices and calculates the differences between the actual values 
and the associated values of roll, pitch, heave and warp 
determined by a desired attitude of the vehicle body to compute 
the desired pressures for the actuators. The degrees of the roll 
and/or pitch differences are set to be higher than that of the 
warp difference in contributing to the determination of the 
desired pressures.

Title: Procedure and equipment for optical spark-emission spectrometry
IPC: G01N21/67
Filed: 1990-05-18
Abstract: In a procedure for optical spark-emission spectrometry in which a spark plasma of a sample is produced in a spark chamber and is evaluated by spectrum analysis using a spectral apparatus connected, in particular optically, to the spark chamber via a connection space, the connection space and the spark chamber having a protective gas continuously flowing through them during a spark process, a flushing pressure is built up in the gas system upstream of the spark chamber. The sudden release of this flushing pressure, for example, before the start of the subsequent spark process brings about a surge-like flow of the volume of flushing gas released in the spark chamber and, consequently, a complete removal of any burn-up residues or air components from the spark chamber. The gas flow can be interrrupted during the standby time. Equipment for carrying out the procedure comprises a spark chamber with an inlet for the flushing gas which can be sealed gastight by means of a shut-off device which can be opened suddenly. <IMAGE>

Cr x O y  particles after a green compact of Cr₂O₃ is formed. 
Alternatively, a mixture of Cr₂O y  particles and Cu particles 
may be formed into a green compact, which may then be 
sintered. Still alternatively, a mixture of Cr₂O y  particles 
and Cu particles may be hot-pressed.

Title: Optical scanning device
IPC: G11B7/095
Filed: 1992-05-04
Abstract: A device is described for scanning an information plane having tracks in which a track to be scanned is tracked by means of the three-beam method. Each one of the three beams is push-pull detected by three split detection systems (10, 11, 12). A position signal Ep which is a measure of the position of an adjustable element (9) in the device determining the transversal position of the spots with respect to the tracks is derived from the detector signals by means of a special electronic circuit (24-26, 30-32).

Title: Data security arrangements for semiconductor programmable logic devices
IPC: G11C7/24
Filed: 1992-09-30
Abstract: A data security arrangement is provided to protect configuration data to be stored in static random access memories (38) in semiconductor programmable logic devices PLD. The configuration data, which is vulnerable to illegal duplication, is normally held in a read only memory ROM, typically an erasable programmable read only memory. A data coding means is provided to code the configuration data to be loaded to the PLD and a data decoding means is provided in the PLD to decode the coded configuration data. The coding and decoding means each incorporate maximal length shift registers (12, 25) which generate a pseudo-random sequence of bits. A key value is input to the shift register (12) in the coding means forcing it to start at a particular point in the sequence. The output (bits B28 and B31) of this register is combined in an EXCLUSIVE-OR gate (20) with configuration data and coded data is written to the read only memory ROM (24). The decoding means in the PLD has a corresponding key value held in a non-volatile memory (28) in the PLD. This is applied to the register (25) of the decoding means whose output (bits B28 and B31) are combined in an EXCLUSIVE-OR GATE (34) with coded configuration data CDIC read from the ROM (24) to produce decoded configuration data CDOD to be sotred in the memories (38). <IMAGE>

Title: Crimping tool for processing wire terminals
Inventor: SCHMODE HARTMUT
IPC: H01R43/042
Filed: 1993-01-20
Abstract: Pliers for dressing conductor ends have two handles (3, 11) which can move relative to one another, a plurality of dressing stations for the conductor ends, and a drive device (21) via which the dressing stations can be driven during operation of the handles (3, 11). One of the dressing stations is constructed as a crimping drum (18) which can be displaced axially and is supported such that it can rotate and be coupled to the drive device (21) in the axially displaced position over only one dressing process. In this position, the station can be locked via a flange (52) which projects radially from it. This flange (52) extends over the overall circumference of the crimping drum (18) and has at least one recess (51). A locking tab (50a), which is arranged in a fixed position on the body (2) of the pliers and is radially opposite the flange (52), engages, in the undisplaced axial position of the crimping drum (18), into the recess (51), to be precise up to a point close to the outer surface of the crimping drum (18) while, in the axially displaced and rotated position of the crimping drum (18), the locking tab (50a) comes to rest above the outer surface of the crimping drum and engages behind the flange (52). Locking of the crimping drum (18) both in the rotational direction and in the axial displacement direction is thus possible by the locking tab (50a).
